Also included is a separate file that includes low resolution copies of all the models in one scene for those who require lower polygon counts. The polygon count listed above is for all the models combined. The individual polygon counts for each model (listed as high res; low res) are as follows: -- 2 blade propeller: 2,918 ; 952 -- 3 blade propeller: 4,548 ; 1,434 -- 4 blade propeller: 5,048 ; 1,712 -- 5 blade propeller: 5,916 ; 1,922 -- 7 blade submarine propeller: 8,586 ; 2,914 Note: Preview images rendered using PhotoView 360 - not required to make models work.
